CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application Nos. 63/267,779 (filed on Feb. 9, 2022) and 63/336,069 (filed on Apr. 28, 2022), the contents of which are incorporated herein by reference in their entireties.

BACKGROUND

The present disclosure relates to medical devices. More particularly, the present disclosure relates to a medical visualization and intubation systems.

Laryngoscopy may be performed for many reasons, such as, for example, to view the interior structure of the throat such as the larynx, to facilitate endotracheal intubation using an endotracheal tube (ETT), to perform a biopsy procedure, etc. Generally, direct laryngoscopy refers to the use of a handheld laryngoscope to view the interior structure of the throat along a direct line-of-sight, while indirect laryngoscopy refers to the use of a laryngoscope in combination with an optical device to visualize the larynx or trachea along an indirect line-of-sight, such as, for example, a mirror or prism, a fiberoptic stylet, a video laryngoscope, etc.

However, for certain medical procedures, direct laryngoscopy often presents challenges that make a direct line-of-sight view difficult due to planned or unplanned scenarios such as anterior vocal cords, obesity, large tongue, or other irregular airway anatomical features.

The video stylet includes a number of wires, a connecter coupled to the wires, a flexible segment, a malleable segment and a video camera coupled to one or more of the wires. The connector is removably attachable to an electronic device. The flexible segment includes a flexible sheath enclosing the wires. The malleable segment includes a malleable sheath enclosing a malleable wire and the wires. The malleable sheath has a smaller diameter than the flexible sheath.

FIG. 1 depicts IS 100, in accordance with an embodiment of the present disclosure.

In many embodiments, IS 100 includes laryngoscope 110, electronic device 120, ETT 130 and LES 200.

Laryngoscope 110 includes handle 112, blade 114 and connector 116 that attaches blade 114 to the lower end of handle 112. Connector 116 may be fixed, or releasable in order to support different sizes and types of blades 114. For example, a portion of connector 116 may be fixed to, or incorporated within, the lower end of handle 112, a mating portion of connector 116 may be fixed to, or incorporated within, the proximal end of blade 114. Blade 114 may be a Macintosh (curved) blade, a Miller (straight) blade, etc., and generally includes a spatula to pass over the lingual surface of the tongue, a flange to displace the tongue, and a tip to lift the epiglottis. Handle 112 is cylindrical in shape with a generally uniform diameter, and has an upper end as well as the lower end.

Electronic device 120 includes display 122 for displaying images from video stylet 210. More particularly, electronic device 120 is a portable, handheld, computer-based electronic device with a touchscreen interface and a data/charging port (e.g., a Lighting port, a USB-C port, etc.), such as, for example, a smartphone (e.g., Apple iPhone, Samsung Galaxy S/A/Z, etc.), a tablet (e.g., Apple iPad mini, Samsung Galaxy Tab, etc.), etc. In some embodiments, electronic device 120 may include a network interface to connect to a cellular network, a WiFi network, etc.

ETT 130 includes, inter alia, tube 132, proximal endcap 133 defining a proximal opening, and beveled distal end 134 defining a distal opening.

LES 200 includes video stylet 210 and holder 220 for electronic device 120. Video stylet 210 includes, inter alia, connector 216 that is removably attachable to the data/charging port of electronic device 120, a flexible segment (depicted in solid line) generally disposed outside tube 132, a malleable segment (depicted in dotted line) generally disposed within tube 132, and video camera 214. The malleable segment of video stylet 210 is deformable into a preferred shape or curvature, and may extend past the proximal end of ETT 130, i.e., outside tube 132. The combination of a flexible segment and a malleable segment in video stylet 210 is advantageously lightweight and maneuvers easily when advancing ETT 130 into the patient's airway with one hand.

FIG. 2 depicts in-situ operation of IS 100, in accordance with an embodiment of the present disclosure.

During an intubation procedure for patient 104, healthcare provider 102 holds handle 112 of laryngoscope 110 in one hand and tube 132 of ETT 130 in the other hand. More particularly, healthcare provider 102 first manipulates video stylet 210 into a preferred curvature, and then inserts video stylet 210 into the opening defined by proximal endcap 133 of ETT 130 such that video camera 214 is disposed proximate to the opening defined by beveled distal end 134 of ETT 130. Once inserted, ETT 130 generally conforms to the curvature of the malleable portion of video stylet 210. With the assistance of laryngoscope 110, healthcare provider 102 introduces ETT 130 into the mouth of patient 104. After initially positioning ETT 130, healthcare provider 102 then advances ETT 130 towards the vocal cords of patient 104 using indirect laryngoscopy, during which time images of the upper airway, captured by video camera 214, are presented on display 122 for viewing by healthcare provider 102.

During a visualization procedure for patient 104, ETT 130 is not used and healthcare provider 102 holds handle 112 of laryngoscope 110 in one hand and video stylet 210 in the other hand. More particularly, with the assistance of laryngoscope 110, healthcare provider 102 introduces video stylet 210 into the mouth of patient 104. After initially positioning video stylet 210, healthcare provider 102 then advances video stylet 210 towards the vocal cords of patient 104 using indirect laryngoscopy, during which time images of the upper airway, captured by video camera 214, are presented on display 122 for viewing by healthcare provider 102.

IS 100 advantageously incorporates the same handheld laryngoscope into these procedures, which allows healthcare provider 102 to perform the same physical movements as before while integrating indirect line-of-sight capability.

FIG. 3 depicts ETT 130, in accordance with an embodiment of the present disclosure.

ETT 130 includes tube 132, proximal endcap 133 defining a proximal opening, beveled distal end 134 defining a distal opening, air supply connector 136, and inflatable cuff/balloon 138. Opening 137 (e.g., a “Murphy eye”) may also be provided at the distal end of tube 132 to prevent obstruction if the distal opening defined by beveled distal end 134 is blocked by mucus or sealed by contact with the patient's tracheal wall.

The proximal opening accepts video stylet 210 for passage through tube 132, while the distal opening allows video camera 214 to extend past beveled distal end 134 (if desired). Generally, tube 132 has an outer diameter and an inner diameter, and ETT 130 has a size (in millimeters) that is based on the inner diameter of tube 132, generally ranging from 3.5 (i.e., 3.5 mm inner diameter, e.g., for small infants) to 8.5 (i.e., 8.5 mm inner diameter, e.g., for adult males), and larger. The sizes are typically specified in 0.5 mm increments.

FIG. 4 depicts LES 200, in accordance with an embodiment of the present disclosure.

LES 200 includes video stylet 210 and holder 220 for electronic device 120.

Generally, video stylet 210 includes connector 216 that is removably attachable to the data/charging port of electronic device 120, a flexible portion, i.e., tube or sheath 212, a malleable portion, i.e., tube or or sheath 213, and video camera 214.

More particularly, FIGS. 5A and 5B depict plan views of video stylet 210, in accordance with embodiments of the present disclosure, while FIG. 5C depicts a cross-sectional view of the flexible segment of video stylet 210, a cross-sectional view of the malleable segment of video stylet 210, and a view of the distal end of video stylet 210, in accordance with embodiments of the present disclosure.

Video stylet 210 has a proximal end, flexible segment 210F, a sheath diameter transition location, a malleable segment 210 m, and a distal end. In many embodiments, video stylet has an overall length of about 33 to 42 inches, flexible segment 210F has a diameter of about 7 to 12 mm and a length of about 16 to 20 inches, malleable segment 210 m has a diameter of about 3 to 6.5 mm and a length of about 16 to 20 inches, and video camera 214 has a diameter of about 3 to 5.5 mm and a length of about 1 to 2 inches.

A number of wires 232 couple connector 216 to video camera 214, and extend through flexible segment 210F and malleable segment 210 m. Generally, the number of wires 232 are determined by a particular electrical communication specification, such as, for example, Universal Serial Bus (USB), etc. Connector 216 is coupled to the wires at the proximal end of video stylet 210. Sheath 212 encloses the wires, and extends along the length of flexible segment 210F, i.e., from connector 216 to the sheath diameter transition location. Sheath 213 encloses a malleable wire and the wires, and extends along the length of malleable segment 210 m, i.e., from the sheath diameter transition location to the video camera 214. Advantageously, sheath 213 has a smaller diameter than sheath 212 to accommodate small diameter ETTs 130.

In certain embodiments, an additional connector 215 may be coupled the wires at the proximal end of video stylet 210. Additional connector 215 may have a different electrical interface than connector 216, and may be coupled to an additional electronic device, such as, for example, a smartphone, tablet, large screen monitor, etc. In other embodiments, the electrical interfaces may be the same for connectors 215 and 216.

Video camera 214 is coupled to the wires at the distal end of video stylet 210. In many embodiments, a light source (not depicted for clarity) may be co-located with video camera 214 and coupled to the wires. In certain embodiments, light source control unit 218 is coupled to one or more of the wires to control the light source, such as, for example, one or more light-emitting diodes (LEDs), etc.

Sheath 212 made be manufactured from solid polyvinyl chloride (PVC) to protect the cables from damage, such as, for example, fraying, etc. Shield 211 may include one or more layers of wire, aluminum foil and/or mylar. Wires 232 may be single or multiple strands of copper wire that are clad with high-resistance insulation material, such as, for example, a dielectric material, etc.; certain wires may be unclad. In many embodiments, the wires include a ground wire, a power wire, and two or more signal wires; the signal wires may be untwisted or twisted pairs.

The cross section for malleable segment 210 m depicts sheath 213, malleable wire 230 and wires 232. Sheath 213 made be manufactured from polyolefin (e.g., heat shrink tubing) to protect the cables from damage, such as, for example, fraying, etc. Malleable wire 230 may be manufactured from a malleable metal, such as, for example, aluminum, etc.; in many embodiments, malleable wire 230 weighs about 16 to 18 grams. Wires 232 may be single or multiple strands of copper wire that are clad with high-resistance insulation material, such as, for example, a dielectric material, etc.; certain wires may be unclad. In many embodiments, the wires include a ground wire, a power wire, and two or more signal wires; the signal wires may be untwisted or twisted pairs.

Advantageously, the diameter of the malleable segment 210 m is smaller than the diameter of the flexible segment 210E due, at least in part, to the absence of shield 211. In certain embodiments, all of the wires 232 may be twisted together to further reduce the diameter of the malleable segment 210 m.

The view of the distal end is a view of the front end of video camera 214 including lens 217. In this embodiment, the light source includes multiple LEDs 219 surrounding lens 217.
